RULIN G MACHINE.

Application filed May 8, 1923. Serial No. 637,418.

This invention relates to machines adapte": t'or ruling parallel straiydrt lines upon ttat sheets.

An object of the invention is to make 5 provision whereby the beginnings and ends of the lines ma be determined with a high degree of accuracy, so as to register with horizontal lines adjusted to horizontal spaces. prorided, or to be provided. upon such sheets.

A further object is to provide a machine of this eharz'icter which can be quickly and aecuratelv adjusted to any length 0t line and to anv width of space between lines. both laterally and end v-rise.

Another object is to make provision tor a machine oi this kind which will automata call operate to etl'ect the result for which it has been set.

So far as I am aware. machines adapted to rule lines upon flat surfaces have heretofore been constructed with pens arranged to deliver tluid ink to the sin-taco to be rulel; and such pens are only adapted to th use oi" tluid inks and they are subject to injury iron] the t'riction ot' the paper or other ma terial which is drawn under the pens.

\l'ith the pen ruling machines, the work otadjusting the pens to the required service is vei'v ditticnlt and requires the attention of a highly skilled workman owing to various ctmditions such as various degrees of pressure on the pens. different stittness oi pens and ditlerent adpistments of the. pens toward and t'rom the surt'ace to be ruled.

An objectot' this invention is to avoid all such ilitliculties and to make it po si )le t'or an ordinal workman to make all adjustments. I p

An object of this invention is to ennunate such frictional wear as might interfere with the accuracy of ruling so that a machine when once set to a certain job will contini e accurate work indefinitely without further attemion. until the job is tinished.

l have discovered that it is pra iiial to ell ect such ruling by means of disks inked with printers ink and this invention is broadly nevi. basic and pioneer in that l have provided rotar disks for the ruling of flat surfaces.

An advantage gained by providing ruling disks instead or ruling pens is the ease at setting the mach ne to the desired ruling spaces.

An object of the invention is ease and accuracy of retting the machine with respe t to both width of space and length of line.

In this respect the invention broadlv new. basic and pioneer in that I have prtivided a disk and a disk holder therefor, the latter being pivotallv mounted above a table on an axis that is arallel to the table surface. and means for holding the disk in position to contact with a table supported ll't tti to be ruled. and with means adapted t ink the edge of the disk.

I have also provided means to hold the disk out ot' ruling position and I make the disk holders and disks thin and flat and mount an desired number ot said disk holders on a common axis. and provide spacers wherebv the disk holders, and conseipientl, the disks may be spaced apart as desired.

Other objects oi the invention are sin plicit and cheapness of construction and ease of assembly and adjustment.

An object of the invention is to so con struct the line ruling elements of the machine as to allow them to be made irom stampings united in a simple and inexpensive manner such as by rivets and electric spot welding.

Other objects. advantages and features of invention may appear from the accompany ing drawings. the subjoined detail description and the appended claims.

The acoompanying drawings illustrate the invention.

Fig. 10 is an enlarged top view of the regular ruling element shown in Fig. 8.

Fig. 11 is an enlarged t agmental top edge view of a multiple line ruling element.

Fig. 12 is a fragmental elevation in se tion on line ;L" :L Fig. at. the gears, rollers and rods being left intact.

The sheet supporting and driving cylinder 1 preferably made of steel and has a perfectly smooth, ground and polished peripheral sun'ace constituting means to su port the sheet (1 as it passes beneath the ruling disks 2 which are opposed to the sheet supporting means. and are jonrnalled in the disk holders 3, that are oscillatably mounted in the horizontal disk holding rock shalt rod at, so that by gravitational means they may be individually moved into commission or ruling position, as shown at 2 at the right of the rod l in Fig. 4; and out. of commis. ion or operative position as a' 2" at the left, of said rod st in laid Fig. 4:. Each disk 2 or 2" and its holder 3 constitutes a line ruling element. Thus each disk is entirely independent trom every other one and need not be adjusted with relation to any other. The disks may be of slightly ditl'crent dianieters and still make a perfectly ruled sheet. since each one rests on the paper independently of every other. This makes tHr simplicity of adjustment and uniformly ac curate work. Also it will be seen that each disk is automatically compensated for w ttl'.

\Yhen one or more disks are in ruling position as shown at 2 in Fig. l. the inking roller 5 is brought into position to rest upon the top edges of the disks so that by such means they are collectively held in comnri, sion or operative position; and during the operation of the disks 2. thcy are inked by the nking roller to which the ink. is distributed in the usual way by the rollers G and T, that are pivotally connected to the inking roller arm 8 by the pivot 9 and arm 10 for roller (3; and the pivot ll and arm 7; said inking roller 5 being 13 to a support it tlXttl that supports thc 12 for roller pivoted by ttXlS to the iratne l5 siX't with.

16, 17 of the table top, and in which frame the shaft 18 of the cylinder 1 is journalled.

The sections it), 17 of the table top are spaced apart from the cylinder 1 so that the produced surfaces of the table sections are tangent to the crown of the cylinder as clearly seen in Fig. l. The sections are also at an angle from the horizontal, so that the paper feeds better, and without a tendency to wrinkle under the disks.

Rollers 19 are mounted in position to rest upon the sheet rt to be ruled, and to hold said sheet against the cylinder 1, thus to insure that the cylinder will any the sheet through the machine. Said rollers 19 are mounted inadjustable roller holders 2t) pro vided with bearings formed by slots 21 spaced from said rollers 19 and adapted to receive the rod '1 upon which the disk holders it are oscillatably and slidably mounted.

Yielding means are arranged to press the rollers 19 down upon the sheet a to he ruled. to hold said sheet friction tight upon the cylinder 1; and such means are shown as a spring 22 connected to a stud 2i} projecting from the roller holder 20 undern ath the slot 21; and the spring 22 secured to the stud 2 3 by any suitable means, as by inserting the end of the spring through a hole 2t in said stud, and detachably connecting it with a horizontal spacer supporting rod 2.3 that is 'arrted by the rear ends of arms tit of rock shaft t. and extends in parallelism with the rods or shafts l, 19, 2G, 27 and 28, the cylinder 1, and the inking and distributing rollers 5, (3 and T. The springs 22 are shown provided with hooks to hook upwn the rod 25 behind the rod -l upon which the disk holder $3 and the roller holders it) turn.

The inking rollers 5, (5 and T, may be removed from the disks 2 and the sheet contacting friction iroducing rollers 15). by swinging the arms in up from the solid linc position. over, back and down to the hanging position shown by the broken line: in Fig. so that any or all the disks and the friction rollers are free to be adjusted alternatively into and out of contact with the sheet as desired.

The regular or permanent spacers il are swung on the lt'tl 25 and are artangcd to be thrown back to rest on the rod 2? and allowed to hang down when not needed indicated at lit) in Figs. 1. l: and the disk holders 3 are arranged to he slid aside when not required for ruling and swung back i. rest on rcd 25 as shown at 25", Figs. 1 and The rod 25 carried by the rear ends of arms forming a yoke (3 which is lined to the rack sha't't t by taper pins 62: and a skipping rod 31% extending transversely beneath the disk holders and roller holders that are in active po ition. is fixed to the front end of the yoke so that by rocking the shalt,

I lit! 4. the disks and rollers may be lifted from or lowered onto the sheet a to oe ruled.

The parts are constructed and arramged to allow the rod 38. at one position, to tcave the rollers and disks free to rest'on the surface to be ruled and to allow said red, when sliehtly raised. to act on the disk holder: to lift the disks from such surface, and, upon a further upward movement of rod 38, to also lift the rollers. These movements of the rod are effected by rock and shaft t and its yoke 63.

The ruling disks and the holders therefor may he constructed in any desired way. Said disks are thin edged as indicated at 2 in Fig. It), and the holders 3 may he made of two side pie es a spot-welded or otherwise fixed to center pieces (I and c; the disks 2 being mounted upon axles riveted to the side pieces I), 0.

The regular disk holders are provided with holes 0 at their ends opposite the disk and are slidahiy strung upon the rod t and held apart thereon by spacers 3t) that have holes 151 at one end by which they are slidably strung upon the spacer rod Said spacers are provided at their freely swinging ends with lateral slots 3:2 adapted to accommodate. hook upon. and freely slide alone. the rod elupon which the disk holders are strung. The sides of the disk holdcrs 3. and spacers 3t) are that and tit closely together so as to hold the disks :3. true. The holders and spacers are slidahte along their respective rods so that they may be brought. to any position desired.

in add tion to the permanent spacers 9t), removable supplemental spacers 353 are provided. each having a lateral slot 32' correspending: to the lateral slot 32 in the permanent spacers, and provided with a rear end slot 2H adapted to accommodate and fit upon the rod 25 so that the spacers of this character can he detachahly inserted wherever desired to appropriately space the disk holders and their disks. Each of the spat crs is provided with a knob 33 by which it can he handled.

When the permanent spacers C30 are not in use, they may he swung over from the rod l and allowed to hang down as seen at 30 in Fig. 4: and when the disks are not in use. they may he caught by their tips 36 and .sWIUtSI hack to rest upon the rod 25 as shown at 2a in Fig. l. Detachable friction pressure roller holders il may perform the otl'iee of spacers as well as that of holding the rollers that press the paper down on cylinder 1. Said roller holders 20 are recessed at their lower edges as at 37 to t2(c()tI)ll=odate a disk lifting skip rod 38 which is carried hy rock arms 63 that are fixed to and extend forwardly from the rod 4 to cause it to act upon the disk holders 3 to lift the disks :2 from the sheet a. for the purpose of simultaneously terminating the ruling by all disks in operation. lu Fig. 5 said skip rod :58 is shown in disk lifting position. the roller it) being shown still in conta t with the sheet (L so that the revolution of the cylindcr advances the paper, thus causing the disks to skip a space.

it; is thus seen that when the skip rod as is down as in Fig. 4, the friction rollers 15) and the ruling disks 2 contact with the sheets (I, and the friction thus produced between the sheet and the cylinder is sntlicient to advance the sheet; and the disks operate to transfer the ink from the inking roller 5 to the sheet; and when the skip rod 38 is lifted slightly it acts upon the disk holders 3 to lift the disks 2. thus stopping the ruling operation without disturbing the rollers which still serve to atlord such friction of sheet upon cylinder as to advance the sheet as the cylinder revolves.

The cylinder shaft 18 and the mechanisn'i cooperating therewith and with the cylinder 1 ar (riven by any suitable power, as by mectric motor 39 through worm it), worm wheel it and power shaft 42 which is connected at one end by intermittent motion mechanism comprising crank arm 43 with crank pin it: adjustable thereon by slot -15 and nut etti; connecting rod 47; pin in; radius arm 4.) of toothed segment 5t) oscillatinc on shaft 51 through pinion 52 and well known ratchet mechanism 53 to operate the cylinder at each revolution of the power shaft 42. through an amplitude olrotary movement determined by the radial position of the pin 4-4.. The cylinder operating mechanism just described old and well known and constitutes no part of my invention,

Referriim to Fig. 2 the skipping cam 54 projects beyond the rim of the graduated cam wheel that is fixed to the power shaft 42 and shown provided with cam holding arcuate slots 56, 5G, and with oraduations 57.

The arcuate slots are of different radii and the cams are each provided with holt holes 58. 58' at a slightly greater distance from the outer ends of the cams than the distance between the slots, respectively. and the circular rim of the cam wheel.

(hie or more cams may he used and the slots overlap so that any cam may he disposed at any desired position on the wheel and se ured by a bolt .79. o that it will actuate the skip har ti as the cam pass s the same.

The tappet ends of the cams may he o-' different lengths and the operator will :u'- range the cams on the skip wheel so as to lift and lower the bar 60 as may he desired to end and begin the ruled lines it.

The skip bar 60 is shown provided on one side with a roller 61 which is long enough to extend across the path of any number of cams that may be stacked and secured on the side of the skip Wheel.

The rear end of the skip bar is fixed by suitable means as the set screw 60 to the rod 4: which constitutes a. rock shaft to which there are fixed, by suitable means, as the tapered pins 62. the rock arms 63 that carry the skip rod 38 which extends under the disk holders 3 and roller holders 20.

The construction and arrangement of the means just described is such that when a cam passes the skip bar and lifts the roller. the (if: .s are lifted and held from the sheet 1; for the exact period of cam passage, thus instantly terminating the ruled lines when the cam lifts, and again instantly continuing the ruling at the moment the cam leaves the skip roller.

The throw-off lever 64 is journaled on the power shaft 42 and is provided with a cam 65 adapted to lift the skip roller 61 when the throw-off lever 64 is pulled forward. and to fre said roller when the throw-off is thrown back. A spring 66 is fixed at one end to a stud 66' which also serves as a rest for the retracted throw-off lever 64 as shown in Fig. said spring 66 is connected to the skip lever 60 above said stud 66' to draw said lever down to hold the skip roller in contact with the periphery of the cam wheel 55 and in contact with the cams 54 as they pass beneath the roller, thus making the operation of lifting the rolling disks instanta neous. The cam finger 65 is shaped so as to lift the roller 61 sufliciently to not only lift the disks from the sheet but also to lift the friction rollers 19 when the throw-off lever is fully moved forward. The spring 67 is arranged. to hold the inking roller firmly down upon the disks. Said inking roller is driven in the usual manner by a toothed wheel 68 meshing with the idler 69 that is carried on the adjusting arm 70 and meshes with the toothed wheel Tl that is fixed to the cylinder shaft 18 which forms the center upon which the arm 70 oscillates.

Said arm 70 is provided with a slot 72 to accommodate a bolt 73 which is fixed to the. frame 15 and is fitted with a tap nut 74 by which the arm 70 is made stationary when the idler is adjusted to cooperate with the toothed wheel 68 when the inking roller has been brought into engagement with the tops of the disks.

The worm shaft is provided with arm on which a crank T6 may be detachably applied to turn the parts to a desired adjustment before starting the machine. 77 indicates an adjustable gage clamped onto the table to direct the paper to pass under the inking mechanism. Such gages may be placed in any position and the machine is adapted to rule one or more sheets of any Width within the limits of the tables width.

It is also adapted to rule a continuous sheet drawn from a paper roll, not shown.

The delivery table 78 is provided with the usual barrier 79 to hold the ruled sheets stacked on the table.

A set screw 8!) is provided to limit the thrust of the inking roller 5 under the ten sion of the spring 67.

Locking collars 81 having slots 82 to receive the rock shaft 4. and having set screw 83 to fix the collar on said rock shaft. are provided to hold the spacers and disk hold ers in the final assembly position to effect the ruling.

The adjustment and operation of the ma chine will be understood from the foregoing description.

Before the machine is put into operation. the set screw will be adjusted to allow the :appropriate pressure of the roller upon the disks; the inking apparatus will be swung back out of the way as indicated in the broken lines in Fig. 2, and the attendant will adjust the disk holders, spacers. rollers and spacing clamps to the required work and will also apply to the skip wheel such cams and length of tappetmay be required to determine the space between the ends of the lines. The operator will lay copy on the table and arrange the ruling disks to correspond in position to the lines on the copy and will swing the permanent spacers into appropriate. position, and where additional spacers are required, will insert the temporary spacers; and when all the parts are thus adjusted he will apply the locking collars 81 to hold the assen'ibly. and will tighten the set screws 83} \Vhen all the parts are ready for operation of the machine, the stack of sheets may be placed on the front section 16 of the table in the usual way. and the sheets may then be fed one by one in the ordinary way to run beneath the disks and rollers; or if it is desired to rule a continuous strip of paper, this may be done. by feeding the paper in a well known manner from a roller, not shown.
